Making earrings or necklaces from bullets?

I shot a couple guns for the very first time today and I'd like to make a pair of earrings or a necklace. I've got two rifle bullets, and 4 pistol bullets.
I'd like the rifle bullets to be earrings, but I'm not sure what to do with the pistol bullets? I also wanted to keep the first pistol bullet separate, but I don't have to. I just really want to make something out of all this brass.

I've never made any jewelry before, especially not earrings, so all the help I can get would be great.
